When it comes to MP3 players the iPod owns the market. I've had an iPod since generation 2 and with the addition of the iTunes music store I have not purchased a CD in quite some time. With all of the songs on my MP3 player it is nice to have a full library of music in my pocket, but when I'm in the car I am limited to my CD player and the radio. Only newer cars have iPod docks so what can you do to get all your music available in your car? Get a FM transmitter, which will transmit the music from your iPod over the radio. Griffin was nice enough to send us their latest version of their RoadTrip FM transmitter, let's check it out!
